2 Claims.

My invention relates to packages of thread, and has special reference tospools for thread and yarn.

In packing certain threads and yarns, such as mending cotton for theretail trade, it has heretofore been customary to wind the thread uponcylindrical paper drums, the thread being wound across the ends of thedrum to provide a ball type package. Such packages, however, have beenfound objectionable in some respects. The uneven surfaces provided bythe cross windings at the ends result in the balls being difficult tostack evenly on the counters or shelves of retail stores, and also thewindings are liable to slough off the ends of the balls while on displayand the thread become soiled or dirty. Moreover, this ball package ismore or less inconvenient in use, the thread being liable to slacken andslip on the paper drum as it is drawn therefrom.

One of the objects of the present invention is to provide a threadpackage which has all of the advantages of the ball package abovedescribed, while overcoming the disadvantages thereof.

Another object of the invention is to provide a novel and improved spoolfor thread and yarn.

Referring to the drawing,

Figure l is a side elevation of my improved thread package in itspreferred form;

Fig. 2 is an end elevation of the same;

Fig. 3 is a longitudinal sectional View, partly in elevation, of myimproved spool; and

Fig. 4 is a detail sectional view, on an enlarged scale, correspondingto a portion of Fig. 3.

The spool illustrated in Figs. 1 to l, inclusive, of the drawing, isprovided with a tubular core 2 and paper disks 4 secured to the ends ofthe core. The core 2 may be made of corrugated newsboard or similarpaper so as to provide a corrugated or otherwise roughened outersurface. Each of the disks 4 has a central countersunk portion 6 and anoutwardly and inwardly curved rim 8 which sets over and is firmlysecured to the end of the core. The inner edge of this rim may project aslight distance beyond the periphery of the core and is directedinwardly so as to provide a threadretaining flange. This rim 8, byextending over the corners of the wall of the end of the core and beingglued thereto, insures that the disk is firmly secured to the end of thecore so that there is no danger of the disks coming off. The concave rimalso serves to reinforce the disk. The inwardly directed edge of the rimprovides an effective thread-retaining means and is so formed that thereis no danger of the thread or yarn catching thereon during the windingof the pack- Serial No. 539,796

age. The rims 8 so reinforce the disks as to insure that they will notbecome bent or distorted while the package is in use so as to allow thethread to catch between them and the ends of the core. The countersunkcentral portion of the disk provides a convenient fiat surface to whicha label 9 may be glued or pasted, the rim protecting the edge of thelabel from being rubbed 01f or accidentally removed. The inwardly turnedrims together with the roughened surface of the core, insure against thethread slipping or sloughing ofi while the package is in use. The rims 8merge into the surface of the wound thread, thus presenting a neat andattractive appearance.

If desired, the end disks may be provided with axially arrangedapertures 10, and a paper band 12 may be secured about the wound thread.

As will be evident to those skilled in the art, my invention permitsvarious modifications without departing from the spirit thereof or thescope of the appended claims.

What I claim is:

1. A spool of the class described comprising a tubular core of paper anddisks of paper secured to the ends of the core, the core being of athickness substantially greater than that of the disks and each diskhaving a counter-sunk por tion set into the end of the core and areinforcing concave rim portion fitted over and glued to the end of thecore, with the inwardly directed edges of the concave rim portionsextending slightly beyond the periphery of the core to provide a threadretaining flange.

2. A spool according to claim 1 wherein said core is of corrugatednewsboard providing a roughened external surface serving, together withthe inwardly directed edges of the concave rim portions of the paperdisks to prevent sloughing oif of thread wound upon the core.
